Learn About Two Basic States of Play in Football

24 Aug 17

Under the laws of football, there are two basic states of play during a game. The states are ball in play and ball out of play. A ball is in play from the beginning of each playing time with a kick – off until the end of the playing period. The ball is in play at almost every time except at two times. Those two times are when either the ball leaves the field of play or the game is stopped by the referee.

The play is restarted by one of the eight restart methods, when the ball becomes out of play. This also depends on how it went out of play. The eight ways are kick-off, throw-in, goal kick, corner kick, indirect free kick, direct free kick, penalty kick and dropped ball. Kick ball happens when you want to begin each period of play. Throw – in is when the ball has crossed the touchline. When the goal line has been crossed with scoring a goal, the goal kick is awarded to defending team while corner kick is awarded to attacking team.

Direct free kick and penalty kick are awarded to fouled team whereas indirect free kick to the opposing team following non-penal fouls. Dropped ball occurs when the referee has stopped play.

Have You Ever Heard About Wheelchair Tennis?

Wheelchair tennis is one of the kinds of tennis developed to be adapted for wheelchair users. Dimensions of courts, balls and rackets are same for both pedestrian tennis and wheelchair tennis. The two major differences in both of them are that athletes use specially designed wheelchairs in wheelchair tennis and the second one is that the ball may bounce up to two times.

The second bound of ball may also take place outside the court. It is played at Grand Slams and it is one of the sports to be organized in Paralympics. The game is played in three categories; Men, Women and Quads. Each category consists of singles and doubles tournaments. The category ‘Quads’ is for quadriplegic players and is sometimes known as Mixed at Paralympic Games. The Players of Quads make use of electric – powered wheelchairs and hold rackets taped to their hands.

The sports received popularity in 1976 by the efforts of Brad Perks who is the creator of competitive wheelchair tennis.

The creative ways to paint, decorate, enhance and embellish the nails is all in Nail Art. It is a kind of artistic work which can be performed on fingernails and toenails. The exact birth of nail treatments is still not clear as it seem to have originated in different parts of world approximately around same time.

Ancient Egypt from 5,000 B.C. to 3,000 B.C. showed some evidences on women dying their nails with henna to display social status. Lower class women painted pastel and neutral shades while upper class women wore deep and bright shades. One will be surprised to know that around 3200 B.C., not women, but men painted their nails with black and green kohl which is an ancient cosmetic. Around same period, 3000 B.C., the first nail polish came out in ancient China.

Nail Care Industry is growing rapidly since the invention of modern day nail polish. The year 2012 gave birth to nail art in USA where its popularity reached peak. Same year released a short nail art documentary which was named as “NAILgasm”.

It’s All about Wrestling- The Game of Power

25 Sep 17

Wrestling is a very ancient sport that was played in various parts of world. Usually it was known as a game to be fit and healthy. At the same time it was also used as a medium to express the authority and power and to punish the wrong doers. In India it is known as “Malla” “Dwandwa” “Dangal” etc. Wrestling is a combat sport that involves grappling type techniques. There are signs of this sport in Veda, the Babylonian and Egyptian civilisation. Presently there are gymnasiums and athletic clubs that present a regulated form of wrestling. It has also found its place in Olympic Games. It is being played by women too. There are Olympic disciplines such as: 1. Greco-Roman wrestling- In this form it is forbidden to hold the opponent below the belt, to make trips, and to actively use the legs in the execution of any action; 2. Freestyle wrestling- It is played by both men and women. This style allows the use of the wrestler's or his opponent's legs in offense and defense; 3. Amateur Pankration- It is a form of Martial Art; 4. Beach wrestling- It is standing wrestling done by wrestlers, inside a sand-filled circle. Its rules have been modified in 2015 that now allows wrestlers to score points through takedowns, pushing their opponent out of bounds, or bringing the opponent down to their back.

The Equation of Undular bore: Formation and Effects

25 Sep 17

“Undular bore” that is also known as Atmospheric Gravity Waves, is an event that occurs when a fluid or a gas is disturbed suddenly. It gives rise to a series of oscillations that propagate and spread. This kind of occurrence happens in various things like water waves and Plasma that are made-up of ionized gases with positively and negatively charged free particles. The same kind of situation occurs in our atmosphere.

We can see the Undular Waves through the amazing cloud formations. Usually low-level atmospheric stability is involved in the formation of Undular bores. A new kind of equation has been formulated to understand what happens when an Undular bore occurs and spreads within two axes. When two air masses of different temperatures collide the Undular bores are formed. When a low level boundary such as a cold front or outflow boundary approaches a layer of cold, balanced and steady air, it causes disturbance in the atmosphere and produces a wave-like force, known as a gravity wave.

At first time in the 1960s, mathematician Gerald B. Whitham attempted to describe Undular bores. Since then research is continued to know its cause and effects. Researchers used the equations to study Undular bores whose wave height varies along only one of the two directions and still trying to apply the equations in distinguishing undular bores whose wave height changes along both axes.

Kayaking: The Technique to Use a Kayak in the Moving Water

24 Sep 17

Kayak is a small and fine watercraft which is moved by means of a double-bladed paddle. The use of a Kayak in the moving water is called Kayaking. Many people confuse Kayaking with canoeing. However, canoeing is completely different from Kayaking.

While using a Kayak the peddler sits facing forward, legs in front, using a double-bladed paddle to pull front-to-back on one side and then the other in rotation. Moreover, most Kayaks have closed decks, although sit-on-top and inflatable kayaks are growing in popularity as well.

Kayaking is forever rewarding. Anyone who wants to learn kayaking can easily learn the tricks because the basic skills can be learned in a day or so. However, one can have fun perfecting those basic skills and learning new ones for years. Kayaking as a hobby provides the basis for a health and fitness lifestyle. Additionally, it is a relaxing activity.

The best part of Kayaking is it can be pursued solo. It is something one can spend a few hours enjoying. Or one can challenge themselves to an expedition of days or even weeks. Kayaking has its health benefits too. As per the health experts, to move the kayak at about 5 mph is going to require about 0.1 hp of effort. This effort is going to use up about 400 calories per hour. And so, four hours of paddling can burn up about 1600 calories.
